Generator

Generators in wind turbines are subject to high vibration loads. This additional permanent load has a negative influence on the cages and places strain on the lubricant.

High speeds

High temperatures

High vibration loads

Risk of the passage of current

Damage due to the passage of electrical currentCurrent passage causes serious bearing damage and thus leads to premature, unexpected failure of a motor or generator:

Craters caused by melting

Molten droplets

False brinelling

Discoloration

Micro-wear

Premature aging of the lubricant

Noticeable noise behavior

Longer operating life due to current insulationCurrent-insulating bearings prevent damage due to the passage of electrical current and thus ensure lower maintenance costs and higher machine availability.

All current-insulating bearings have the same dimensions and load carrying capacities as those without insulation, which makes them perfectly interchangeable.
